The Big Apple remains the place to do business for the world’s biggest hedge funds. Forty-five of the world’s largest 100 hedge funds are based in New York City, according to Alpha magazine’s annual rankings. Those funds manage $664.5 billion of the $1.35 trillion in assets under management in the top 100, or just under half the total. Including its suburbs—11 hedge funds based in southwestern Connecticut, plus one each in Long Island, New Jersey and Westchester County—the New York area boasts 59 of the top 100 funds, managing $812.5 billion, or 60% of the top 100’s assets.

New York City—home to the world’s largest hedge fund, JPMorgan Asset Management—has five of the top 10 hedge funds and 10 of the top 20. Including its suburbs, those numbers rise to seven of 10 and 13 of 20. Last year, the city was home to four of the top 10, with its suburbs accounting for another three.

London ranked second with 19 of the top 100 hedge funds, managing a total of $273.2 billion. All told, just 23 of the biggest hedge funds are based outside of the U.S., with one each in Bermuda, Paris, Tokyo and Zurich, Switzerland.

That leaves 77 funds with $1.05 trillion in assets based in the U.S. Boston is home to seven giant funds (after New York City and Connecticut), followed by California with three and Chicago with two. Birmingham, Ala., Dallas, Minnetonka, Minn., Pittsburgh, St. Francis, Wis., and Towson, Md., each boast one top 100 fund.
